Weiler® Tiger® AO type 1 portable snagging wheels deliver the right combination of performance and value. Aluminum oxide grains in combination with a strong bond deliver long product life and a consistent cut rate when grinding. To ensure maximum product safety, these wheels are designed with three layers of fiberglass reinforcement. The reinforcement also reduces edge chipping and promotes more consistent product wear. The type 1 shape features a flat face with a narrow contact area, making them ideal for targeted heavy grinding and stock removal applications. These 3 in snagging wheels are designed for use on die grinders. The 3/8 in arbor hole includes a precision phenolic resin insert to ensure a tight fit on the tool, minimal vibration and an enhanced operator experience.
